Several Warning Messages this Morning

[Amendale]

The last time I have driven my car it was perfectly fine. Since my last drive I had left for vacation and left the Model 3 sitting in my garage for a week (plugged in). Upon my return I was greeted with several warning messages as soon as my foot hit the brake pedal:

- Automatic emergency braking disabled;
- Car needs service: steering assist reduced;
- Traction control disabled;
- ABS needs service;
- Regenerative braking not available;

In addition the steering is very heavy, I am guessing the power steering is disabled.

I have spoken to Tesla chat support and they advised to do a power reset through the Safety and Service settings, but it did not help. I am going to go to a SC to see what the issue is. In the meantime, has anyone experienced this issue that was not solved by a reset? What was the culprit?

The disconnecting the 12V battery for a few minutes and reconnecting it, might clear the errors you’re experiencing.

Are you speaking from experience or is this a guess?

I got the regenerative breaking one then it went away. I don’t recall exactly where the message was, but it was somewhere on the left side of the screen.

If you search the various threads in the forum related to your issues you’ll find anything from 12V battery issues to issues with the main battery. If it was me and it was safely driveable I’d take it to the SC or see if you can have a mobile ranger come to you. Good luck.

Just a guess. You’re not going to harm anything doing this though.

And you know this won't cause any harm how?

This happened to me a few weeks after taking delivery last summer, took it to the SC, they replace my steering control module. It’s been 9+ months since then and I haven’t had any issues.

It’s just the 12V battery. I’m not suggesting trying to disconnect the main battery pack. The 12V battery will need to be replaced eventually as it does on all cars. If the 12V completely dies and has no charge left that’s no different than disconnecting it from the car. It’s one of the very few parts of the car that an owner can replace themselves. I only suggested it since it’s possible that disconnecting it may clear the error codes the OP is getting if a power off from the menus was not successful.

UPDATE: Called the SC this morning, they expedited my appointment and took it immediately. Faulty wheel speed sensor. Diagnosed and replaced the sensor, and had my car back within 4 hours. They were also kind enough to give me a complimentary car wash, cleaned out my floor mats, adjusted tire pressure, and topped of window washer fluid. So far I have had an excellent experience with Tesla service/customer support.
